Toshiba Launches New High Capacity 1.8-inch HDD

Toshiba Storage Device Division today announced its largest capacity
1.8-inch (4.6cm) form factor HDD in a 5mm height to date. At 220 GB
the MK2239GSL single platter SATA HDD offers the highest capacity per space available in a 1.8-inch (4.6cm) form factor HDD.

Its super slim frame of just 5mm makes the MK2239GSL ideal for use in
compact mobile devices. These include digital video recorders (DVC),
personal media players and compact external HDDs as well as media
tablets, notebook PCs, mini-notebooks and ruggedised laptop PCs.

Toshiba has shipped over 80 million 1.8-inch HDDs to date. A recent
report from IDC shows that in Q3 2010, Toshiba shipped over 92 per
cent of the 1.8-inch HDDs worldwide, retaining its number one market
share position since entering the market in 2000.

The MK2239GSL is part of a new line of 1.8-inch (4.6cm) HDDs, which
are the first to be developed with LIF SATA connector, enabling
Toshiba to produce a drive up to 10 per cent smaller foot print than
those with micro SATA connector. The MKxx39GSL HDD series has also
been developed using long sector formatting, an advanced format
technology that Toshiba has used since 2007 due to its ability to
increase storage capabilities. This combination of both LIF SATA and
long sector formatting enables Toshiba to produce HDDs that provide
both a high quality performance and large capacity, yet are still
portable and compact.

The MKxx39GSL line of HDDs includes the following products: the
MK1639GSL, the MK2039GSL and the MK2239GSL, all with capacities of
160GB, 200GB and 220GB respectively. However, these large capacities
do not mean a compromise on energy efficiency. With an energy
consumption efficiency of 0.0016W/GB, the MK2239GSL
uses 30 per cent less power than previous models such as the
MK1634GSL. It not only surpasses its 1.8-inch predecessor in energy
efficiency, but also in 2.5-inch form factor as well. The lower power
consumption of the MK2239GSL will increase battery life, essential
for mobile multimedia devices such as notebook PCs or tablets, which
are often used to view video and TV content and play music, requiring
longer battery durability.

Weighing just 48 grams, it can withstand up to 1,500 Gs of
non-operational shock and 600Gs operational shock, a vibration
robustness that surpasses even 2.5-inch form factor durability. Each
HDD also has a high buffer memory of 16MB and interface transfer rate
of 1.5 Gb/sec.
